ENE? AT SADDLE.

To all whom it may concern:

Be it known that I, CHARLES A. PERSONS, a citizen of the United States,residing at IVorcester, in the county of Worcester, State ofMassachusetts, have invented a certain new and useful Improvement inSaddles, of which the following is a specification, reference being hadtherein to the accompanying drawings.

This invention relates to resilient seats or saddles, but moreparticularly to such as are u'lsed on velocipedes, bicycles or othervehi- 0 es.

For simplicity and clearness in the following description, the devicewill be treated in connection with bicycle saddles, but it should beclearly understood that it may be applied to any seat or saddle.

ne of the objects of this invention is to provide a saddle having thehighest vibration absorption, and whose efiiciency is uneffected by thetilting of the same from its horizontal position.

In the ordinary form of bicycle saddle, the springs consist of one ormore sections of spring wire running from front to rear and passingthrough a clamp. The introfor greater comfort in riding has led to theintroduction of compound spring seats. These generally comprise a singleor double loop of spring wire at the front or peak of the saddle, and apair of compound springs, each consisting of a compression and anextension spring, to support the cantle. Heretofore these compoundsprings have been arranged concentrically with the compression springwithin the extension spring to allow the use of comparatively longsprings without danger'of buckling. Such a form would probably operatesatisfactorily in a fixed horizontal saddle, but when the latter istilted, the compression spring chafes on the extension spring.

The applicant has devised a compound coil spring in which thecompression and the extension springs do not act within one another, butwhich will not buckle.

One form of this device consists of a pair of extension springssuspended from the arms of a truss having upright rods or posts attachedto the ends of these springs to support the compression springs, and asupport or bridge connecting these posts.

Specification of Letters Patent.

Application filed May 25, 1908.

Patented May 31, 1910.

Serial No. 434,911.

It should be clearly understood that the applicant does not limit hisinvention to this construction and arrangement of parts, as they may bematerially varied without effecting the result.

It is generally advisable to construct the extension spring a littlestronger than the compression spring or vice versa, to procure the dashpot or damping effect, although this is not essential.

To allow the saddle to be tilted to a convenient angle, an adjustableclamp may be fastened to the truss to attach the saddle to the saddlepost. Heretofore numerous forms of clamps have been devised, but theseusually allow tilting, if at all, by merely loosening the clamping boltand tilting the saddle.

One form of the applicants device shows an adjusting screw by means ofwhich the saddle may be moved to any convenient angle and held there inabsolute safety, as will be more fully shown and described hereinafter.This clamp thus contains an adjusting screw, also serving as a means forpreventing accidental revolution of the sad dle on the clamping bolt.

One embodiment of the invention is shown in the accompanying drawings inwhich 1*- Figure 1, is a side view of the invention complete. Fig. 2,rear view of same. Fig. 3, front view of clamp, to be describedhereinafter. Fig. 4, side view of same, portions removed to show adusting screw. Fig. 5, modification of compound spring. Fig. 6,

modification of compound spring. Fig. 7, truss detached from saddle, tobe described hereinafter.

In the drawings, the seat 1 is attached at its peak 2 to the spring 3,having a double loop at 4, the other extremity of the spring 3 beingfastened to the frame 5 at 6.

The frame is shown as composed of two trusses 7 and 8, as shown in Fig.7 and these are fastened together by the clamp bolt 9 at approximatelytheir center. At the extremities 10 and 11 of the trusses 7 and 8respectively, are suspended the extension coil springs 12 and 13, theupper ends of the same being clamped to the trusses by the bolts 11 and15 respectively. At the lower or free ends 16 and 17 of the springs 1).and 13 respectively, are attached upright rods or posts 18 and 19extending upward within I I ma the coils. These posts may be anyconvenient lengths, but it is generally advantageous to make themsufliciently long to normally maintain the support or bridge 20 atsufficicnt height that the latter may not come in contact with the topof the extension springs 12 and 13 when the saddle is in use.

The posts 18 and 19 and the bridge 20 are shown in one piece in Figs. 1and 2, but these may be separate parts as shown in Figs. 5 and 6. InFig. 5, the bridge is bolted to the upper extremities of the posts 18and 19 by extending these posts through apertures in the bridge, andthreading the ends of the posts to allow nuts to be placed thereon.

Fig. 6, shows an advantageous modification of the bridge 20 where a wideseat is to be used. The rod is extended beyond the junction of the postsand itself to form projecting arms 23 to support the compressionsprings, described hereinafter.

The compression coil springs 21 and 22 are attached at their lower ends24 and 25 to the bridge 20 at or near its extremities, and the upperends of these springs 21 and 22 are attached to the cantle 26 at 27 and28 by bolts or other suitable means.

To support the rear extremities 10 and 11 of the trusses 7 and 8respectively, a brace 29 is placed between them, as shown in Figs. 1 and2. This brace is referably curved to allow the saddle post of a bicycleto pass beneath and thus permit the saddle to be tilted. Care should betaken that this does not extend upward or inward sufficiently tointerfere with the action of the seat.

Upon the clamping bolt 9 is a collar 30 to grasp the saddle post whenthe saddle is placed upon the bicycle. The tightening of the clampingbolt contracts this collar, when the saddle is upon the post, andprevents side revolution or tilting. The collar is provided with ears 31and 32 having apertures to contain a pin 33 connecting these ears. Tothis pin 33 is fastened the adjusting screw 34 which is threaded to meshwith a tapped hole in the hexagonal headed screw 35, the latter beingthreaded also on its outer surface to mesh with a tapped hole in the pin36, connecting cars 37 and 38 on the trusses 7 and 8 respectively. Thehexagonal headed screw 35 is preferably threaded right on its inner walland left on its outer wall which prevents accidental movement of theadjusting screw and also causes the latter to advance a considerableamount on a slight turn of the former. To operate this clamp, the nut 39on the clamping bolt 9 should be loosened, the hexagonal screw turned totilt the saddle in the proper direction, and the nut 39 tightened whenthe saddle is in place.

It should be clearly understood that the invention is not limited tothis construction and arrangement of parts in the clamping device, asthe same might be greatly altered without changing the principlesthereof.
